Series 17 Miniature LED Indicators FEATURES: Mount in wide range of panel thicknesses Choice of chrome or black chrome finish Single, bi-, and tri-color LED illumination Meet IP40 or IP67 specifications

1. See "Dimensions & Mounting Information" for details of reflector style.
2. "Chrome" and "Black" refer to Bright Chrome and Black Chrome bezel colors. Except where noted black chrome bezels are an option, bright chrome are standard.
3. Sunlight Readable LEDs offer increased intensity.
4. Boldface part numbers are stocking items. Non-stocking items require a 100 piece minimum or a 15% adder to the price if less than 100 pieces are ordered.
5. 130 VAC and 230 VAC models are supplied with an insulating sleeve for electrical shock protection.

Series 17 LED indicators can be obtained in four different reflector styles, five mounting hole dimensions, four operating voltages, and a variety of LED colors. The resulting panel-mounted indicators are attractive and easy to install.

The Series 17 indicators come complete with lens and LED; simply order the model that fits your needs. In addition to the standard models listed, there are many optional voltages, LED colors, and LED intensities available plus two-color, three-color, and flashing indicators.

Options
Many electrical, mechanical, color, and other options are available as non-stocking items. The following section describes some of the variations and special features that are available.

Non-stocking items require a 100 piece minimum order. If less than 100 pieces are ordered, a 15% additional charge is added to the price.

Additional voltages
In addition to the standard voltages offered 6, 12, 24, 28, 36, 48, and 60 volt models are available in selected series. These models use internal dropping resistors to operate at various voltages. Models operating at approximately 2-3 volts (no resistor) also are available.

Reflector style
In addition to the typical external, internal, flat front, and standard reflectors shown, conical and flush mount reflectors can be obtained with some models.

Sealing
16 and 22 mm indicators are sealed to IP 67 using gaskets around the LED and between the bezel and panel.
  6 mm models are sealed to IP 40.
  8 and 14 mm models are sealed to IP 40 but can be obtained sealed to IP 67 on special request.

Additional colors and intensities
In addition to the common LED colors, there is a wide selection of special colors and color variations available ir Series 17 indicators. In addition, new color LEDs are currently being developed for all types of applications.

Special high intensity indicators also can be produced utilizing special reflectors, lenses, or advanced high intensity LED chips, alone or in combination.

Bi-Color and Tri-Color LEDs

Bi-Colors are available in red/yellow, green/yellow, and red/green models. By using two separate color LED chips, they display one of the two colors depending on electrical input as shown below.

In addition, a 2-pin bi-color that changes color when polarity is changed is available on special request. Tri-Colors also use two LED chips (red and green) selected such that when both chips are energized a yellow light is obtained. These models display red, green, or yellow depending on the electrical input as shown below.

Flashing models
There are many applications that require the attention alert obtained with a flashing light. Series 17 flashing LED indicators are available in a number of configurations, colors, and styles.

The flashing frequency is a function of voltage and can be varied from 1.5 to 2.5 Hz in some models by varying the supply voltage from 3.5 to 13 volts. Other models have a fixed flashing rate.

Other options
1. A special plastic housing can be supplied for high temperature applications. It extends the typical working temperature from 70°C to as high as 210°C.
2. Indicators are not electrically protected for polarity reversal. This feature can be obtained on request.
